The perovskite manganites with generic formula RE 1− x AE x MnO 3 (RE= rare earth, AE=
Ca, Sr, Ba and Pb) have drawn considerable attention, especially following the discovery of …

The magnetocaloric effect describes the change in temperature of a magnetic material under
adiabatic conditions through the application or removal of an external magnetic field. This …

The development of ferromagnetism in Mn-doped Bi 2 Te 3 is characterized through
measurements on a series of single crystals with different Mn content. Scanning tunneling …

A universal curve for the change in the magnetic entropy has been recently proposed for
materials with second-order phase transitions. In this work we have studied the universal …

The critical behavior at the paramagnetic to ferromagnetic phase transition in Pr 0.5 Sr 0.5
MnO 3 is studied using techniques such as modified Arrott plot, Kouvel-Fisher plot, and …

Magnetic oxides show a variety of extrinsic magnetotransport phenomena: grain-boundary,
tunnelling and domain-wall magnetoresistance. In view of these phenomena the role of …

We report on the do** dependence of the order of the ferromagnetic metal to
paramagnetic insulator phase transition in L a 1-x C ax M n O 3. At x= 0.33, magnetization …

Abstract The La 0.67 Sr 0.33 MnO 3 composition prepared by sol–gel synthesis was studied
by dc magnetization measurements. A large magnetocaloric effect was inferred over a wide …

The nature of ferromagnetic phase transition and its critical properties in La0. 7Ca0. 3−
xSrxMnO3 (x= 0, 0.05, 0.1, 0.2 and 0.25) single crystals have been studied systematically …

The novel all-d-metal Ni (Co) MnTi based magnetic Heusler alloys provide an adjustable
giant magnetocaloric effect and good mechanical properties. We report that the second …
