The eight Inner Triplets of the LHC will each house a combined corrector magnet assembly, MQSXA, which comprises a skew quadrupole (MQSX) in line with nested skew octupole (MCOSX), octupole (MCOX), and skew sextupole (MCSSX) windings. These supercond

The magnetic and transport properties of Tl2Mn2−xRuxO7 pyrochlores are analyzed as a function of the substitution rate (0⩽x⩽2). For x⩽0.2, the system exhibits colossal magnetoresistance (CMR) and ferromagnetic ordering. For higher doping rate
