Low temperature susceptibility compensation
First Claim
1. In a magnetic resonance apparatus for study of a sample, said apparatus comprising the environment surrounding said sample wherein said environment is characterized by a first value of magnetic susceptibility, an amorphous composition comprising an amorphous matrix, a metal ion selected from the group consisting of Gd3 +, Fe+3 and Mn+2, and a ligand, said composition having a value of magnetic susceptibility substantially equal to said first value at cryogenic temperatures.

Abstract
An composition exhibiting a desired value of magnetic susceptibility, which can be used to fabricate components in an NMR device, and method thereof, wherein the composition comprises a metal ion selected from the group consisting of Gd+3, Fe+3 and Mn+2 and an amorphous material using a ligand or chelating agent to solubilize the metal ion throughout the marphous material, wherein the magnetic susceptibility of the composition exhibits a desired value at cryogenic temperatures such as nearly zero susceptibility at temperatures at or below 77° K.
