Abstract
- The ESR spectrum of a powder sample of the metal-organic complex Cu(C<subscript>10</subscript>H<subscript>8</subscript>N<subscript>2</subscript>)(H<subscript>2</subscript>O)<subscript>2</subscript>SO<subscript>4</subscript> is investigated in the temperature interval 2–30 K. It is found that the orbital ground level of the Cu<superscript>2+</superscript> ion in this compound is the Kramers doublet |x<superscript>2</superscript>-y<superscript>2</superscript>>. The temperature dependences of the effective g-factor components and of the resonance linewidth ΔH of individual powder particles are obtained. Low-temperature broadening of the resonance line connected with short-range magnetic order in the system is observed. An estimate of the value of the exchange coupling in the magnetic system is made. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
