Large magnetocaloric effect and adiabatic demagnetization refrigeration with YbPt2Sn

Large magnetocaloric effect and adiabatic demagnetization refrigeration with YbPt2Sn

Adiabatic demagnetization is currently gaining strong interest in searching for alternatives to (3)He-based refrigeration techniques for achieving temperatures below 2 K. The main reasons for that are the recent shortage and high price of the rare helium isotope (3)He. Here we report the discovery of a large magnetocaloric effect in the intermetallic compound YbPt2Sn, which allows adiabatic dem...

A Miniature Adiabatic Demagnetization Refrigerator with a Magnetoresistive Heat Switch

We present the design of a novel, miniature ADR with no moving parts, which could be used to cool detectors for astrophysics research, semiconductor analysis, and mass spectrometry. The miniature ADR relies on the development of a magnetoresistive heat switch. We present measurements of the thermal conductivity of a single-crystal tungsten heat switch at temperatures below 4 K and magnetic fiel...

A 24-Gd nanocapsule with a large magnetocaloric effect.

Two 24-nuclear lanthanide clusters, and were obtained and structurally characterized. Magnetic investigations reveal that exhibits the largest entropy change (-ΔS(m)) of 46.12 J kg(-1) K(-1) for ΔH = 7 T in all reported molecular clusters, and single-molecule magnet behaviour is observed in .
