Magnetic properties of orthorhombic T-phase Al-Pd(Fe)-Mn - members of complex metallic alloys - with different Pd(Fe)/Mn atomic ratios were studied experimentally. The measured zero field cooling-field cooling splitting, the frequency dependent AC susceptibility and slow thermoremanent magnetization time decay indicate that the samples possess built-in frustration-like properties similar to those in spin glasses.
