Special Issue Information

Dear Colleagues,

A ferroelectric can spontaneously polarize if exposed to an electric field without the application of a voltage, and its polarization state can be altered by varying its voltage. Since Valasek first discovered ferroelectricity in Rochelle salt 100 years ago, this class of materials has been extensively studied. Since perovskite oxides are the most used ferroelectrics, they are known to have issues with scalability and compatibility with CMOS, which has impeded their wider application and development. In the field of ferroelectrics and related applications, discoveries of ferroelectricity in novel materials systems such as doped hafnia, AlxSc1-xN and 2D materials have caused considerable interest. In this issue, material scientists and electrical engineers present their cutting-edge research on novel ferroelectrics.

In this Special Issue, we will collect papers on the integration of ferroelectric materials in sensors and other devices. This Special Issue encourages professors and scientists to submit their pioneering research.

  1. Ferroelectric material-based chemical sensors.
  2. Ferroelectric material-based biosensors.
  3. Ferroelectric material photonics sensors and devices.
  4. Magnetic devices.
  5. Spintronics devices.
  6. Ferroelectric material medical devices.
  7. Ferroelectric material fundamental properties.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
We study the structural, magnetic, and magneto-thermal properties of the GdRhIn compound. The room-temperature X-ray diffraction measurements show a hexagonal crystal structure. Temperature and field dependence of magnetization suggest two magnetic transitions—antiferromagnetic to ferromagnetic at 16 K and ferromagnetic to paramagnetic at 34 [...] Read more.
We study the structural, magnetic, and magneto-thermal properties of the GdRhIn compound. The room-temperature X-ray diffraction measurements show a hexagonal crystal structure. Temperature and field dependence of magnetization suggest two magnetic transitions—antiferromagnetic to ferromagnetic at 16 K and ferromagnetic to paramagnetic at 34 K. The heat capacity measurements confirm both the magnetic transitions in GdRhIn. The magnetization data were used to calculate isothermal magnetic entropy change and refrigerant capacity in GdRhIn, which was found to be 10.3 J/Kg-K for the field change of 70 kOe and 282 J/Kg for the field change of 50 kOe, respectively. The large magnetocaloric effect in GdRhIn suggests that the material could be used for magnetic refrigeration at low temperatures. Full article
