Magnetocaloric effect in Gd microwires
نویسندگان
چکیده
In Gd microwires obtained by ultrafast cooling of the melt, a change in magnetic entropy 12 J/kg K was determined at Curie temperature 293 field 5 T. This value coincides with part bulk single-crystal samples same field. It has been found that strong 9 T, dependence exhibits two maxima temperatures 292 and 312 K. The appearance an additional maximum microstructured is caused high mechanical microstresses retained sample after cooling. Keywords: microwires, entropy, magnetoelastic anisotropy, temperature.

In this work we calculate the magnetocaloric effect in the compounds Gd5Si4 and Tb5Si4. We use a model Hamiltonian of interacting spins, and treat the spin–spin interaction in the Monte Carlo simulation. The theoretically calculated isothermal entropy change and the adiabatic temperature change upon variation of the magnetic field are in good agreement with the available experimental data. The ...
متن کاملMagnetocaloric effect and thermal conductivity of Gd(OH)3 and Gd2O(OH)4(H2O)2.
Magnetocaloric effect (MCE) and thermal conductivity of two gadolinium hydroxides, Gd(OH)3 (1) and Gd2O(OH)4(H2O)2 (2), are investigated. Magnetic studies indicate that both 1 and 2 exhibit antiferromagnetic interaction, and the MCE values for 1 and 2 at 2 K and ΔH = 7 T are 62.00 J kg(-1) K(-1) and 59.09 J kg(-1) K(-1), respectively. Investigation of their thermal conductivity reveals that the...

The polycrystalline manganite La0.75Sr0.25MnO3 prepared by an alternative carbonate precipitation route reveals the rhombohedral perovskite structure. Magnetization isotherms measured up to 2 T are used to determine Curie temperature of 332 K by means of Arrott plot. Maximum of magnetic entropy change is found at Curie temperature. The relative cooling power equal to 64 J/kg for 1.5 T magnetic ...
