By incorporating inert KCl into the NaIrO+ 2CuCl → CuIrO+ 2NaCl topochemical reaction, we significantly reduced the synthesis temperature of CuIrOfrom the 350 °C reported in previous studies to 170 °C. This adjustment decreased the Cu/Ir antisite disorder concentration in CuIrOfrom ∼19% to ∼5%. Furthermore, magnetic susceptibility measurements of the present CuIrOsample revealed a weak ferromagnetic-like anomaly with hysteresis at a magnetic transition temperature of ∼70 K.

A nuclear clock based on this nuclear-transition frequency is expected to surpass existing atomic clocks owing to its insusceptibility to surrounding fields. In contrast to other charge states, triply charged Th (Th) is the most suitable for highly accurate nuclear clocks because it has closed electronic transitions that enable laser cooling, laser-induced fluorescence detection and state preparation of ions.

Methods: The participants were 12 patients with right hemisphere damage and 12 patients with left hemisphere damage. The line bisection test, a sit-to-stand movement, and balance assessment were performed before and after the intervention.
