Abstract
Susceptibility and specific heat results are presented for the warwick ite compounds Mg1+xTi1-xBO4. This one-dimensional magnetic material is characterized by the presence of ribbons along the c-axis where the m agnetic Ti3+ ions are randomly located. The low-temperature susceptibi lities are given by chi (T) proportional to T-alpha with the exponent a weakly dependent on Its temperature dependence is well described by C proportional to T1-alpha where alpha is the susceptibility exponent.
