Heat capacities of three magnetic salts near their critical points
… data have been obtained to T-TA = ±3 x 10 TA The magnetic entropy has been found for the latter two salts. The results of these measurements are compared with the work of others on magnetic phase transitions and liquid-vapor phase transitions. Agreement with existing theories is discussed. These …

EXPLORATION OF NEW MULTIFUNCTIONAL MAGNETIC MATERIALS BASED ON A VARIETY OF HEUSLER ALLOYS AND RARE-EARTH COMPOUNDS
Magnetic, magnetocaloric, magnetotransport and magnetoelastic properties of Ni-Mn-X (X = In, and Ga) Heusler alloys and La-Fe-Si based rare earth compounds have been synthesized and investigated by x-ray diffraction, magnetization, strain, and electrical resistivity measurements. The phase …

Doping Studies of Frustrated Magnets
Doping nonmagnetic materials is known as an effective way of investigating the properties of frustrated magnets. LiCuSbO4 is one of the simplest quasi-one dimensional spin-1/2 magnets which can be modelled with ferromagnetic(FM) nearest neighbour and antiferromagnetic (AFM) next nearest neighbour …

Tuning Strong Correlated Properties in EuTiO3 Thin Films Grown by Pulsed Laser Deposition
… attracted intensive attention for achieving ferromagnetic-ferroelectric (or multiferroic) and magnetoelectric coupling via strain engineering. Besides phase transition induced by strain engineering, there is an increasing interest in exploring the magnetocaloric effect (MCE) in ETO-based bulk …

Caloric effects in ferroic materials
… LCMO’s intrinsic caloric effect near its ferromagnetic transition is small (-1.2 J kg−1 K−1 T−1 ) [1]. Moya et al. have discovered that LCMO thin films grown on BaTiO3 (BTO) substrates can produce extrinsic magnetocaloric effects as large as -9 J kg−1 K−1 T−1, driven by a structural phase …

EXPLORATION OF NEW MAGNETOCALORIC AND MULTIFUNCTIONAL MAGNETIC MATERIALS
The magnetic properties of NiMnGe1−xAlx, Ni50Mn35(In1−xBx)15, Ni50Mn35In14.5B0.5 (Bulk, As-Solidified and Annealed melt-spun ribbon) and RE-Infuse Carbon Nanotubes, have been studied by x-ray diffraction, differential scanning calorimetry (DSC), and magnetization measurements. Partial substitution …
