Design of thermal hysteresis in nonstoichiometric alloys with giant magnetocaloric effect
Sagar Ghorai, Rebecca Clulow, Johan Cedervall +12
The non-stoichiometric FeP-type (FeMnPSi)(FeV) alloys ( , , and ) have been investigated as potential candidates for magnet…
Effect of small cation occupancy and anomalous Griffiths phase disorder in nonstoichiometric magnetic perovskites
Sagar Ghorai, Vitalii Shtender, Petter Ström +2
The structural, magnetic, magnetocaloric and Griffiths phase (GP) disorder of non-stoichiometric perovskite manganites La_(0.8-x) Sr_(0.2-y) Mn_(1+x+y) O_3 are reported here. Deter…
Effect of reduced local lattice disorder on the magnetic properties of B-site substituted La0.8Sr0.2MnO3
Sagar Ghorai, Sergey A. Ivanov, Ridha Skini +2
Disorder induced by chemical inhomogeneity and Jahn-Teller (JT) distortions is often observed in mixed valence perovskite manganites. The main reasons for the evolution of this dis…
Field induced crossover in critical behaviour and direct measurement of the magnetocaloric properties of La0.4Pr0.3Ca0.1Sr0.2MnO3
Sagar Ghorai, Ridha Skini, Daniel Hedlund +2
La0.4Pr0.3Ca0.1Sr0.2MnO3 has been investigated as a potential candidate for room temperature magnetic refrigeration. Results from X-ray powder diffraction reveal an orthorhombic st…
Evolution of Griffiths Phase and Critical Behaviour of La1-xPbxMnO3+-y Solid Solutions
Sagar Ghorai, Sergey A. Ivanov, Ridha Skini +1
Polycrystalline La1-xPbxMnO3+-y (x = 0.3, 0.35, 0.4) solid solutions were prepared by solid state reaction method and their magnetic properties have been investigated. Rietveld ref…
