Magnetic resonance as a local probe for kagomé magnetism in Barlowite Cu4(OH)6FBr
Magnetic resonance as a local probe for kagomé magnetism in Barlowite Cu4(OH)6FBr
Abstract Temperature- and field-dependent 1 H-, 19 F-, and 79,81 Br-NMR measurements together with zero - field 79,81 Br-NQR measurements on polycrystalline samples of barlowite, Cu 4 (OH) 6 FBr are conducted to study the magnetism and possible structural distortions on a microscopic level. The temperature dependence of the 79,81 …
