摘要: Abstract The heat conductivity of amorphous (Pd 77.5− x Cu 6 Si 16.5 )Co spin glass alloys containing = 0−15 at% Co is measured with high accuracy (⪅ ± 0.3%) in the temperature range 0.3 ≤ T 25 K and magnetic fields 0 B 5 T. For higher concentrated (“cluster glass” region) results clearly show existence a contribution thermal resistance phonons.
