Abstract:
A rare earth regenerator material particle and a regenerator material particle group having a high long-term reliability, and a superconducting magnet, an examination apparatus, a cryopump and the like using the same are provided. A rare earth regenerator material particle contains a rare earth element as a constituent component, and in the particle, a peak indicating a carbon component is detected in a surface region by an X-ray photoelectron spectroscopy analysis.

Claim (Index 16):
A method for manufacturing a cold head, comprising:\n preparing at least one regenerator container; and filling a plurality of regenerator material particle groups which are different types in the regenerator container, wherein a generator material particle constituting at least one of the plurality of the regenerator material particle groups is a rare earth generator material particle comprising a rare earth element as a constituent component, a peak indicating a carbon component and a peak indicating a compound containing the rare earth element and oxygen are detected in a surface region of the rare earth generator material particle by an X-ray photoelectron spectroscopy analysis, an entire content of carbon in the rare earth generator material particle including the carbon component is 5 mass ppm or more and 100 mass ppm or less, and the carbon component detected in the surface region of the rare earth generator material particle has at least one selected from the group consisting of a C\u2014C bond, a C\u2014H bond, a C\u2014O bond, a C=O bond, and an O\u2014C=O bond.
