In many quantum materials, strong electron correlations lead to the emergence of new states
of matter. In particular, the study in the last decades of the complex phase diagram of high …

The origin of the pseudogap region below a temperature T* is at the heart of the mysteries of
cuprate high-temperature superconductors. Unusual properties of the pseudogap phase …

The iron-substituted FeSr2YCu2O7. 08 cuprate displays long-range magnetic ordering
below TN∼ 140 K, involving both Fe3+ cations in the charge reservoir block (CRB) and …

It has been proposed that the pseudogap state of underdoped cuprate superconductors may
be due to a transition to a phase which has circulating currents within each unit cell. Here …

We present an extended zero-field muon spin relaxation (ZF-μ SR) study of overdoped Bi 2+
x Sr 2− x CaCu 2 O 8+ δ (Bi2212) single crystals, intended to elucidate the origin of weak …

Hidden magnetic order in the correlated iridate Sr 2 Ir 1− x Rh x O 4, x= 0.05 and 0.1, has
been studied using muon spin relaxation spectroscopy. In zero field (ZF) and weak …

We report muon spin relaxation (μ SR) measurements of optimally doped and overdoped Bi
2+ x Sr 2− x CaCu 2 O 8+ δ single crystals that reveal the presence of a weak temperature …

We report the results of a muon spin relaxation study of slow magnetic fluctuations in the
pseudogap phase of underdoped single-crystalline YBa 2 Cu 3 O y, y= 6.77 and 6.83. The …

Substitution of copper by iron in the charge reservoir block of the YSr 2 Cu 3 O 6+ δ (YSCO)
cuprate superconductor brings out an appealing insight on the interplay between …

In this thesis, we theoretically examine the pairing mechanisms and the identification of the
pairing symmetry of unconventional superconductors whose normal states are correlated …
