We present the results of the investigation of magnetic properties of the series. For small doping values, the ordering temperature decreases linearly with , while the moment configuration remains the same as in the parent compound. Around doping level, we observe a change in the behavior, where the ordering temperature starts to increase and new magnetic Bragg peaks appear. For the first time, we present evidence of a long-range order (LRO) in () below mK. It is revealed that the moment configuration corresponds to a Palmer-Chalker type with a value of the magnetic moment significantly renormalized compared to . We discuss our results in the framework of a possible quantum phase transition occurring close to .
