“…In the range of a few Kelvin and below, however, the fluctuation rate approaches a constant non-zero value, preventing spin freezing. Such a behavior of persistent spin fluctuations suppressing magnetic order has been observed in other materials under the influence of strong Kondo interaction, for example in CeNiSn [17].…”

“…Based on macroscopic studies, possible transitions involving some kind of ''weak'' magnetism were reported at 12 K (Takabatake et al, 1990) and below 0.5 K (Aliev et al, 1993), but no definitive conclusions could be drawn. Additional information was provided by SR measurements (Kalvius et al, 1995). Zero-field studies on single crystals established the absence of a magnetic transition down to at least 0.011 K. This was inferred from the absence of a spontaneous ϩ frequency or a rapidly depolarizing signal.…”

“…Hence it was speculated that hole-hole exchange coupling could lead to an antiferromagnetic ground state. In order to test such a hypothesis, SR studies have been performed on the system Ce 0.85 La 0.15 NiSn, which corresponds to the La concentration for which the energy gap is destroyed (Kalvius et al, 1995).…”

The author attempts to give a comprehensive discussion of studies performed with the positive-muon spin rotation and relaxation technique (also known as the SR technique) on heavy-fermion compounds. The subtle competition between the demagnetizing Kondo interaction and the intersite Ruderman-Kittel-Kasuya-Yosida exchange interaction is believed to be the primary ingredient for the wealth of different ground states observed for this class of rare-earth-and actinide-containing intermetallic compounds. Due to its microscopic character, its sensitivity to extremely small internal fields, and its capacity to detect spatially inhomogeneous magnetic features, the SR technique has been extensively utilized to investigate the peculiar magnetic properties of these ground states and improve our knowledge of heavy-fermion phenomena. In addition to providing a short introduction to SR, where the intrinsic difficulties of the method are clearly stated, this article reviews the main results obtained by this technique on the best-known heavy-fermion compounds (superconductors, band magnets, local-moment magnets, non-Fermi-liquid systems, and Kondo insulators). Special emphasis is placed on the particular information obtainable by monitoring the implanted muon. [S0034-6861(97)00104-9] CONTENTS I. Introduction 1119 A. Puzzle of heavy-fermion physics 1119 B.

“…Recently, charge-ordering phenomena in transition-metal oxides has attracted considerable interests in physics community, since there is an assumption for some common phenomenon concerning a charge stripe formation which were observed in the O-doped or Sr-doped nickelates [1,2], in the cuprates [3][4][5], and high-temperature superconducting cuprates, or giant magnetoresistance in manganites [6][7][8]. In the nickelates, the charge stripes have been observed to be static, at least for certain compositions.…”
