Name and address of institute Hokkaido Research Institute, N19 W11 Kita-ku,

Sapporo, JAPAN

Name of contact person/email Shigeki Hirano/[e-mail]

Year of production 2009 (modi ed in 2013)

Type Rotary

Maximum frequency 4.5 Hz

Maximum cooling power 150 W

Maximum temperature span 5.5 K

Type of AMR Packed bed

MC material(s) Gd and Gd alloys

type of magnets Permanent (Nd - Fe - B)

consisted of a rotating AMR ring and a stationary permanent-magnet assembly. The
AMR ring consisted of Gd particle beds. The magnet assembly could induce a
magnetic

uid was air. The researchers from the
University of Applied Sciences of Western Switzerland exhibited the prototype at the
industrial fair in Hannover and won

eld of 0.8 T. The heat-transfer fl
