Effect of magnetic and non-magnetic impurities on the spin dimers in the spin 1/2 chains of quantum magnet Sr${}_{14}$Cu${}_{24}$O${}_{41}$

Rabindranath Bag, Koushik Karmakar, Sudesh Dhar +3

We study the effect of impurities on the two types of spin-dimers in the hybrid chain/ladder spin 1/2 quantum magnet Sr${}_{14}$Cu${}_{24}$O${}_{41}$. Four different impurities were used…
