Frustrated Spin

Muon-spin relaxation (µSR) has been applied to investigations of slow dynamics and quasi-static features of geometrically frustrated spin systems. We take an example in the Kagome-lattice anti-ferromagnets, and briefly review µSR works on S = 1, 3/2, and 5/2 Kagome compounds. PACS No.: 75.30

Theoretical Results

We discuss several examples of three-dimensional critical phenomena that can be described by Landau–Ginzburg–Wilson ϕ4 theories. We present an overview of field-theoretical results obtained from the analysis of high-order perturbative series in the frameworks of the ∊ and of the fixed-dimension d=3 expansions. In particular, we discuss the stability of the O (N)-symmetric fixed point in a generic N-component theory, the critical behaviors of randomly dilute Ising-like systems and frustrated spin systems with noncollinear order, and the multicritical behavior arising from the competition of two distinct types of ordering with symmetry O (n1) and O (n2) respectively.
