Development of Mn/Mn and Mn/Mg High Temperature TE Devices

Materials Today: Proceedings, 2018
Abstract Skeleton-type 20-pair MnSi1.74/Al3Mn3Si4 and MnSi1.74/Mg2Si devices, usable below 600°C, are fabricated successfully. Ni top-electrodes are brazed to the p- and n-thermoelectric (TE) blocks. 50 x 40 x 2mm3 metallic bases are used. The TE-blocks, 10x3x7 mm3 in size, are cutout from the 30mm ϕ x 7mm pellets synthesized by the spark plasma ...

Inverse magnetocaloric effect in ferromagnetic Ni–Mn–Sn alloys

Nature Materials, 2005
The magnetocaloric effect (MCE) in paramagnetic materials has been widely used for attaining very low temperatures by applying a magnetic field isothermally and removing it adiabatically.

Assessment of the Mobility of Mn in the Fe-Mn and Ni-Mn Binary Systems

International Journal of Materials Research, 2000
The mobility data of Mn that is considered important among the Fe-base alloy system are assessed. The mobility parameters were obtained on the Fe-Mn and Ni-Mn binary systems of which experimental diffusion data were available. The parameters of the self diffusivity and the tracer diffusivity were assessed, and the interdiffusivity have been optimized ...

Mn interstitial diffusion in (ga,mn)as.

Physical review letters, 2004
We present a combined theoretical and experimental study of the ferromagnetic semiconductor (Ga,Mn)As which explains the remarkably large changes observed on low-temperature annealing. Careful control of the annealing conditions allows us to obtain samples with ferromagnetic transition temperatures up to 159 K.
