Language eng - English Country RU - Russian Federation Keywords cobaltates ; specific heat ; magnetic phase transition ; A-type antiferromagnetism Subject RIV BM - Solid Matter Physics ; Magnetism CEZ AV0Z10100520 - FZU-D (2005-2011) UT WOS 000271946300011 DOI 10.1063/1.3253404 Annotation A sharp lambda type anomaly in the specific heat of high-quality single-crystals of NaxCoO2 (x = 0.73, 0.76, 0.77, 0.78 and 0.87) in magnetic field up to 10 T was observed only for x = 0.76 at temperature 21.8 K. Influence of the magnetic field applied perpendicularly and parallel to the CoO2 layers indirectly supports the idea of A-type antiferromagnetic ordering in studied systems.
