Two dimensionality in quasi-one-dimensional cobalt oxides
Magnetism of quasi-one-dimensional (1D) cobalt oxides A n + 2 Co n + 1 O 3 n + 3 ( A = Ca , Sr and Ba, n = 1 –5 and ∞ ) was investigated by μ + SR using polycrystalline samples, at temperatures from 300 K down to 1.8 K. The wTF– μ + SR experiments showed the existence of a magnetic transition in all...

using polycrystalline samples, at temperatures from 300
