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…
Giant magnetocaloric effect in the (Mn,Fe)NiSi-system
Sagar Ghorai, Rafael Martinho Vieira, Vitalii Shtender +7
The search for energy-efficient and environmentally friendly cooling technologies is a key driver for the development of magnetic refrigeration based on the magnetocaloric effect (…
A setup for direct measurement of the adiabatic temperature change in magnetocaloric materials
Sagar Ghorai, Daniel Hedlund, Martin Kapuscinski +1
In order to find a highly efficient, environment-friendly magnetic refrigerant, direct measurements of the adiabatic temperature change is required. Here, in this work,…
Site-specific atomic substitution in a giant magnetocaloric FeP-type system
Sagar Ghorai, Johan Cedervall, Rebecca Clulow +9
Giant magnetocaloric (GMC) materials constitute a requirement for near room temperature magnetic refrigeration. (Fe,Mn)(P,Si) is a GMC compound with strong magnetoelastic coupl…
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…
