cent studies related to the origin of the colossal magnetoresistance effect in perovskite manganites focused on the forms of inhomogeneous phases and the preformation of ferromagnetic (FM) clusters in the paramagnetic (PM) region.[1,2] This clustered state called ‘‘the Griffiths phase’’ (GP) often occurs in the temper
