Magnetocaloric Effect and Sign Reversal of Magnetic Entropy Change Across the Spin Reorientation Temperature in R3Fe5O12 (R = Gd, Dy)
(Elsevier, 2020-04-15)
The cubic structure with space group Ia3‾d for Gd3Fe5O12 and Dy3Fe5O12 are successfully synthesized and the magnetic behaviors are studied in details. The dc magnetization measurements show that an obvious negative ...
Spin Reorientation, Normal and Inverse Magnetocaloric Effects in Heavy Rare-Earth Iron Garnets
(Elsevier, 2020-08-01)
Experiments for heavy rare-earth iron garnets Ho3Fe5O12 and Er3Fe5O12 show a compensation effect characterized by a near zero magnetization at 134 K and 80 K, respectively. The magnetic entropy change calculated according ...
Negative Magnetization and Inverse Exchange Bias Effect Induced By Modulating the Relative Proportion of Mn in Gd 2 Co 2−Xmnxo6 Perovskites
(Physical Review, 2023-06-28)
The magnetic properties of Gd 2 Co2−x Mnx O6 by modulating the relative proportion of Mn are experimentally investigated in this paper. The experimental results indicated that an intrinsic effect of negative magnetization ...
