Both LDH compounds are paramagnetic above about 8\u2009K. A rapid increase of their magnetic moments occurs below this temperature until the moments reach the maximum values at Tmax of 4.0\u2009K and 3.2\u2009K for Co(2)Al\u2013NO3 and Co(3)Al\u2013NO3, respectively. Below Tmax, the zero-field-cooled and the field-cooled static magnetization curves are strongly different. Along with this low-temperature phenomena, Co(2)Al\u2013NO3 and Co(3)Al\u2013NO3 demonstrate anomalous behavior of their temperature dependence magnetic susceptibility in a higher-temperature range: between 75 and 175\u2009K, both the paramagnetic Curie temperature and the effective magnetic moment change in a non-monotonous way. Possible structural reasons of the observed magnetic behavior of the CoII(n)AlIII LDHs are discussed.<\/jats:p>","DOI":"10.1063\/1.5001299","type":"journal-article","created":{"date-parts":[[2017,10,5]],"date-time":"2017-10-05T18:22:00Z","timestamp":1507227720000},"page":"977-981","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":12,"title":["Magnetic phenomena in Co-containing layered double hydroxides"],"prefix":"10.1063","volume":"43","author":[{"given":"Daniel E.
