Magnetoelectric coupling and exchange bias effects in multiferroic NdCrO3.
TL;DR: The rare occurrence of an exchange bias effect in both the magnetic and electric polarizations associated with a strong magnetoelectric coupling is of fundamental interest, as well as being attractive for technological applications close to liquid nitrogen temperature.

Natural ferroelectric order near ambient temperature in the orthoferrite HoFeO 3
K. Dey,A. Indra,Sohini Mukherjee,Subham Majumdar,J. Strempfer,O. Fabelo,E. Mossou,Tapan Chatterji,Saurav Giri +8 more
TL;DR: In this article, the authors reported a natural ferroelectric order around 210 K along the $c$ axis with a reasonably large polarization of 0.29 ± 0.5% for a 10 kV/cm poling field.
Thermally assisted and magnetic field driven isostructural distortion of spinel structure and occurrence of polar order in CoCr 2 S 4
K. Dey,A. Karmakar,A. Indra,Subham Majumdar,U. Rütt,O. Gutowski,Martin v. Zimmermann,Saurav Giri +7 more
TL;DR: In this paper, the authors reported the appearance of polar order with a ordering temperature of 28 K, which is well below the ferrimagnetic order at 225 K for the oxide spinels.
Critical behavior and reversible magnetocaloric effect in multiferroic MnCr2O4
TL;DR: In this paper, the authors investigated the magnetocaloric effect in multiferroic cubic spinel MnCr2O4 (space group Fd (3) over barm, no. 227, cF56), using dc magnetization studies.

CrO 4 distortion-driven ferroelectric order in ( R , Y ) CrO 4 ( R = Sm , Gd , and Ho ) : A new family of multiferroics
A. Indra,K. Dey,J. K. Dey,Subham Majumdar,U. Rütt,O. Gutowski,Martin v. Zimmermann,Saurav Giri +7 more
TL;DR: In this paper, a multiferroic family of tetrahedra is reported and the ferroelectric ordering temperatures are observed at much higher temperatures than their corresponding magnetic ordering temperatures for all the members.
