Magnetocaloric effect and refrigerant capacity in Sr-doped Eu8 Ga16 Ge30 type-I clathrates
(AIP Publishing, 2010-04-19)
Magnetic properties, the magnetocaloric effect (MCE) and refrigerant capacity (RC) were investigated in Eu8Sr8−xGa16Ge30 (x=0,4) type-I clathrates. The substitution of Sr for Eu decreases the Curie temperature (TC) and ...

Laser Dynamics from a Membrane Computing Perspective
(IMCS. International Membrane Computational Society, 2018)
Modelling real systems and processes is a task classically performed through the approach of di erential equation systems, de ning the evolution of di erent variables as the di erent components of the system. A bad feature ...

Ball milling as a way to produce magnetic and magnetocaloric materials: a review
(Springer Nature, 2017)
Ball milling (BM) is a well-established technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (e.g., definition of an ...

Crystallization kinetics and soft magnetic properties in metalloid-free (Fe, Co)90Zr10 amorphous and nanocrystalline alloys
(Elsevier, 2014)
Microstructure and magnetic properties of metalloid-free (Fe100- xCox)90Zr10 amorphous and nanocrystalline alloys were characterized. Devitrification of these amorphous alloys occurs in two overlapped transformations leading ...

Excellent magnetocaloric properties of melt-extracted Gd-based amorphous microwires
(AIP Publishing, 2012-09-06)
We report upon the excellent magnetocaloric properties of Gd53Al24Co20Zr3 amorphous microwires. In addition to obtaining the large magnetic entropy change (-DSM rv 10.3 J/kg K at TC rv 95 K), an extremely large value of ...
